WlRE-NETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 483,182, dated September 2'7, 1892.

Application filed November 16 1891.

To all whom it may concern.-

Be it known that I, HENRY K. SwINsooE, of Clinton, county of Worcester, State of Massachusetts, have invented an Improvement in Wire-Netting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In my experiments to cheapen the cost of production of netting for fencing, &c., without lessening its practical value I have devised a machine having two independentlyactuated racks which may be moved for different distances, thereby enabling the twistingsegments containing the wires for the main body of the netting and rotated by one of the racks to be rotated twice, while the segments carrying the selvage-wires and the segments having wires which are to be wrapped or twisted about the selvage-wires may be rotated three or, it may be, more times by the other rack, thus producing a netting having its body-wires united by a different number of twists than are its selvage-wires.

Onepart of my invention therefore consistsin a wire-netting machine containing the following instrumentalities, viz: sliding carriages, a series of twisting segments carried by said carriages, actuating devices for some of the said segments, and independent separate actuating devices disconnected therefrom for other of the said twisting-segments, whereby some of the segments may be rotated independently of other of the said segments, as will be described.

Other features of my invention will be more specifically described, and pointed out in the claims at the end of this specification.

Figure 1 in front elevation, partially broken out, shows a sufficient portion of a wire-netting machine with my improvements added to enable my invention to be understood; Fig. 2, a right-hand end View thereof; Fig. 8, a longitudinal section in about the line as, Fig. 1, showing parts of the sliding carriages, some of the-twisting-segments, and the two racks, part of the top rack being broken out to show the under rack below it. Fig. 4 shows the opposite ends of the inner edge of the back carriage and some of the pairs of twisting-segments. Fig. 5 is a view similar to Fig.

Serial No. 412,065. (No model.)

3, but with the carriages and racks in their opposite strokes; and Fig. 6 is a view of Fig. 5, similar to Fig. 4.

The framework A, the mesh-roll B, the takeup roll 0, and the carriages D E, connected by a lever F, pivoted on a stand F, are and may be all substantially as usual in wire-netting machines, the contiguous faces of the said carriages containing notches for the reception of twisting-segments to be described.

The twistiiigsegments ordinarily used with sliding carriages such as shown are toothed just alike, and commonly the said teeth are from bottom to top, filling the space between the upper and lower walls of the carriages; but in some instances the said segments have had teeth on their shanks for but a portion of their length; but in such cases the lower sides of the projections having the teeth have rested on the lower part of the carriages and all the teeth have been in the same horizontal plane, so that one and the same rack might rotate all the said segments.

In devising my improved machine for the manufacture of my novel wire-netting Ihave had to depart from heretofore usual constructions and have provided some of the twistingsegments with teeth occupying a different horizontal plane from the teeth of the other segments, I in the present form of my invention having provided the segments a. of the front and back carriages-viz, the segments which carry the wires used in the body of the netting and not twisting with the selvagewire-with teeth '2, which occupy a position close to thebottom partof the slidingcarriages. Others of these segments, especially the two segments 1) b, which carry body-wires and which are located near the ends of the series of segments a a, one of the segments 1) being in one carriage when the other segment I) is in the other carriage, and the selvage-carrying segments 0 and o and the dummy-segment (marked d) will have their teeth 8 in a different horizontal plane from that occupied by the teeth 2, so that one rack, as the under one 6, may engage the teeth 2 of the segments a, while the teeth 3 in the segments 1), b, c, c, and d are shown as located at a higher level, so as to be engaged by the teeth of the rack f, lying, as shown, on the rack e. All the segments carried normally by the front the selvage-segments c and c are supplied with wire 3 4, as is usually the case with wires taken from bobbins or spools c 0 The rack e is shown as joined by a link 6 to a rack-operating device, shown as a lever pivoted at 6 The rack f is shown as joined by a link f to a rack-operating device f shown as a lever pivoted at f The rack-operating devices represented are of the simplest form known to me; but in practice it will be understood that I may, instead of the devices shown, employ any other usual or suitable actuating devices for the said racks so long as they are so made or constructed as toenable the said racksto be reciprocated different distances and at the same or different times, it being understood that to do this the actuating devices to turn the segments more or less are and must be disconnected from each other. The front carriage D is joined by link on to a lever m, so that as said lever is moved, in this instance by hand, the two carriages will be moved simultaneously in opposite directions. Instead, however, of the hand-lever as an operating device for the said carriages, the carriage D may be actuated in any usual or suitable manner.

In' Figs. 1'; 3, and'5 I have omitted from the central partfof the carriages some of the segments at. Iiet it be assumed that all the segments except the dummy d have wires, the two segments 0 and 0' having selvage-wires. Figs. 1 and 3 show the front carriage as moved fully to the left, together with both racks, and the selvage-segment c opposite the dummy d and segment 0' in the back carriage. In this condition the front carriage by the operative device m will be moved to the right, and the segments carried thereby will assume the positions shown in Fig. 5. Then both racks will be moved to the right, and in so doing all the segments will be rotated; but by moving the rack f farther than the rack c it results that the segments 0 and b, as one pair at the left in Fig. 5, and the segments 0 and b at the right, as another pair, are twisted a greater number of times, so that if two twists are given to the segments a three twists or more, if desired, may be given to the segments 0 b e Z). This done, the carriage D willbe shifted to the left, putting the segments in the position Fig. 3, the racks e and f moving to the left on the carriageD. Then in that position of the segments the racks e and f will be moved to the right, but this time for equal distances, so as to put into the wires two twists. At this time it will be noticed that the twistin g-segment c is opposite the dummy d, which is like the segment 0, only that it has not a wire, and that the segment 0 is standing by itself and the segments Z1 and Z) are opposed to segments a a. In this position the selvage wires are not twisted with any other wire. After this the carriage D is again shifted to the right into the position Fig. 5; but at this third stroke the two racks e and f, instead of being shifted to the right, as before described, are shifted to the left and the rack f for the greater distance, so as to rotate the segments a and b and o and b. one or more times more than the segments cm. The carriageD is next slid to the left, carrying with it the rackse and f, putting the segments again in the positions shown in Fig. 3, and the racks are again moved to the left, but only far enough to r0- tate all the segments twice. The next movement will be a repetition of the first of the four movements just described. v

The mesh-roll B may be actuated in any usual way to take up the wire-netting as pro duced, and as fast as made the netting 'will be wound on the take-up roll 0.

My invention may be applied to machines capable of putting reverse twists into the meshes, the machine in such case containing suitable clamping devices as, for instance, such as provided in United States Patent N 0. 387,739, dated August 14, 1888, and granted to B. Scarles-and in this latter instance, owing to the fact that the segments 0 and b and c and b may be moved independent of the body-wire segments a,.I may, if desired, unite the selvage-wire to the body-wire by a series of twists in one direction and ,unite the body-wires by a series of reverse twists.

In my application, Serial No. 393,608, filed May 21, 1891, I show a wire-netting machine containing main and auxiliary carriages, each having its own proper segments, and the said segments are each actuated byits own proper rack, and it is obvious that I might apply my present invention to the machine shown in said application and put more twists into the meshes at one side than into the meshes at the other side of the same row of meshes-as, for instance, more twists into the wide-mesh part of the fabric than into the narrow-mesh part of the fabric. 80, also, it isobvious that by collecting at one end of the pair of carriages segments like a and at the other end segments like those marked b b c c I might make a fabric in which the twists at one part of one row of meshes might have, say, two twists and the other parts three twists.

The particular means for moving the segments are, as herein shown, rack-bars; but instead of these rack-bars I might use any other suitable moving device adapted to engage and rotate the selvage-segments independently of the body-segments, and thus impart to each of the said segments greater or less motion, as desired.

I am aware that it has been proposed in a machine to put less twist into the wires carried by the segments containing the selvage Wires than in the wires carried by the segments provided for producing the body of the fabric; but in such planthe segments containing the body-wires were actuated by toothed surfaces connected directly with and receiv ing their motion from the lever or device which actuates the toothed surfaces for rotating the segments containing the body-wires, and hence in such plan the movements were not independent, although some of the segments were rotated more than others.

This invention is not limited to the exact form of twisting device for uniting the parallel wires nor to the particular means shown to support the said twisting devices in order that the wires may be twisted alternately with each other.

The selvage-wires are commonly larger than the body-wires with which they are united in the production of netting, and hence the selvage and body wires do not twist alike when being united; but on the contrary the selvagewire remains substantially straight and substantially all the twist appears in the bodywire, and that wire is wrapped, as it were, about the selvage-wire, and consequently the netting made from the body-wire slips on the selvage-wires and destroys the symmetry of the meshes. To overcome this slipping, I have, as stated, devised a machine to put more twist at the selvage than at the mesh joining. The additional friction due to a greater number of twists of the body-wire about the selvage-wire produces a joint which will not slip; and the number of extra twists may, it is obvious, be increased as desired, provided the mesh is of proper length.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a machine for the production of wire netting, the following instrum'entalities, viz: sliding carriages, a series of twisting-segments carried by said carriages, actuating devices for some of the said twisting-segments, and independent separate actuating devices disconnected therefrom for others of the said twisting segments, whereby some of the seg ments may be rotated independently of the other of the said segments and in different ing the body-wires, and separate independent actuating devices for the remaining or selvage-wire segments, said latter actuating devices being disconnected from the actuating devices for the body-wire segments, whereby the travel of each of said actuating devices may be varied independently and one series of the said segments may be rotated more than the other series of said segments, substantially as and for the purpose described.

A wire-netting machine containing the following instrumentalities, viz: a series of twisting devices for the wires to be twisted together in the production of the netting, the gears of one of the said series of twisting de vices being in a different horizontal plane from the gears of the other of the said series of twisting devices, supports for the said twisting devices, and independent rack-bars, one for actuating one of the said series of twisting devices and the other to actuate the other of the said series of twisting devices, and disconnected mechanism to move each of the said rack-bars independently one of the other in either the same or opposite directions, substantially as described.

4. In a wire-netting machine, shifting carriages provided with a series of twisting-seg ments mounted therein, combined with two independent rack-bars having their teeth in diiferent horizontal planes and separate and disconnected means to actuate the said rackbars to rotate some orothers of the said twisting-segments, as desired, and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
